IMO, the Nuforce IEM's are the absolute most comfortable IEM I've ever used. The EDC's and Primo 8 IEM's I have literally are so damn comfortable that I honestly forget that they're in my ears. Seriously!

So I'd grab these and sit back and enjoy every second of them!

That said, I Just bought the Primo 8 IEM's, and I was also looking at the Nuforce HEM 2 IEM's, which are single BA Drivers per ear and also around $100. I definitely see myself buying these just because I have loved everything I've gotten from Nuforce, and they're sound, fit, isolation and overall package of accessories is hard to beat!
